4 Claims.

This invention pertains to metal siding units and, more particularly, to interfltting units by means of which the'side walls of buildings may lbe covered with a minimum of leilort and ex-` sists of a plurality of horizontal rows of spaced bricks with the alternate rows longitudinally oiset so that the conventional staggered eiect oi.' brickwork is secured.

` Il Another object of the invention is to so form the upper edges of the units thatvthey will interlock and form a water tight joint one with the other.

A still further object is to iill the rear face de- 8O pressions of the siding withv ilreproof and heat insulating material so that when the units are applied a storm, heat and re proof building results therefrom.

In the drawings: I Fig. 1 is a plan view showing the interlocking of two units; a

Fig. 2 is a. plan view of a plurality of units slightlyseparated from one another to illustrate the manner in which they may be interiitted; I Fig. 3 is a vertical cross section taken on line 3 3 of Fig. 1;

Fig. 4 is a rear plan viewof a fully nished unit;

Fig. 5 is a rear plan of a unit after it has been I insulated, but before the application of the nreproof backing element;

Fig. 6 is an enlarged cross sectional detail showing the interlocking edges of two units; and Fig. 7 is an enlarged top plan view of a siding unit showing the interlocking tongue structure. The units I' are generally rectangular in shape and from a practical standpoint they are preferably made up to represent two horizontally spaced bricks in three horizontal courses with the center course staggered in relation to the first and third course. The middle or alternate row of "bricks consequently present unbroken surfaces overlapping the vertical edges of the "bricks in the upper and lower rows. From a continuous roll of skelp or sheet metal, the individual units l are pressed out in such a manner that the outwardly projecting brick-likje areas 2 are vertically and horizontally spaced by margins 3 simulating "mortar lines in the form I of depressions surrounding the individual (Cl. l89-86) "bricks. These spaces or margins 3 extend around the outer edges of the units, as indicated by the numeral 4, so that when laid up the extending areas of successive units 4 will overlap one another. f

The upper or top edge of each unit, indicated by the numeral 5, is composed of an onset upstanding margin 6 bent back upon itself at 'I and` again bent back at 8 in spaced relation to portion 6. The upper end of the portion l is turned at right angles at 9 and the extreme end Il is bent to lie in spaced parallel relation to the front surface of the unit. Thus the top edge of the unit forms a complete locking means for both longitudinally and vertically successively fitted units. As shown, nail holes are provided in the locking strip 5 and also in the margins 4. As shown in Fig. 6, the lower margins 4 of the succeeding units lie between the walls i and 8 with the wall I0 extending upwardly beyond and of reater length than the folded walls 8 8. As shown, the right-hand edge of the top locking wail is cut-oi! flush with the margin 4, while the left-hand edge is extended at Il to overlap the flush edge of gie succeeding unit when assembled on a dwell- 'I'he outer edges or margins 4 ofthe upper units are offset and cooperate with successive units. As illustrated in Fig. 6, the margin is folded or bent back upon itself at I2 with the free end il of the margin turned at'a 90 angle which contacts with surface4 9 on the lower units.

After the base metal portion of the units hasbeen stamped out, including the top locking edge 5 and marginal areas 4, the undersides of the depressions 2 .created by .the pressing operation are filled with a heat insulating material il, such as mineral wool, mica or the like. Ihe rock wool or other material is extended to completely iill the back of the unit up to the top of the edge I3 and in practice this is approximately one inch in depth. To insure that the heat insulating material will adhere to the insides of the depression and in the slightly depressed areas l. it is preterable to spray or coat the entire inside of the unit with asphalt. A rear reresistant sheet I0 made of asbestos or the like is thereupon placed over the back of the unit and completely covers and retains lthe insulation .I5 in place. The backing sheet is readily held in place by contact with the n asphalt on the rear of the margins or may be retained by inwardly bent ears II struck out o!e the material of edging I 3.V

In applying units of the character described,

it is only necessary to line up a lower horizontal ul series thereof and after nailing the lower line in place the other units are readily placed in position and will always be properly aligned.

As shown in Fig. 2, the middle staggered or oil?- l set course of depressions interflts with the middle course or adjacent units, while the locking members' 5 and tongues Il interengage to support and lineup the units. Nail openings are preferably formed, as illustrated in Fig. 2, and as succeeding units are intertted, they are nailed through margins 6, 1, 4 and 5.

'I'he exterior surfaces of the units-are adapted for any desired treatment, but this is preferably done by spraying or dipping the units to cause asphalt or other adhesive material to adhere on the exterior faces of the depressions 2 and thereafter applying brick granules or the like I8 to give a nish which is difficult to discern from brick construction, and by a simple strip- `n ing device, the vertical and horizontal division lines or depressions 3 may be colored to simulate.

mortar.

What I claim is: 1. A building unit comprising a sheet metal Il plate having a plurality of horizontally pressed out portions extending over the plane thereof and laterally extending anges formed on the top and bottom edges of said unit, the said flange portions lying in substantially the same plane as ,n the unpressed portions of the plate, the ange portion on the upper; edge of said plate forming one side of a channel member positioned thereon, and the ilange portion'on the lower edge of the plate forming a cooperating member for engagement with the channel member of an adjacent y ing illed with mineral wool and a reproof backing sheet extending substantially throughout the area of the rear of the unit.

4. A building unit comprising a sheet metal plate embossed to simulate bricks with mortar joints therebetween, the unit being surrounded on its periphery by a flange lying substantially in the plane of the mortar joints, the flange on the upper edge of said unit having a continuation thereof bent downwardlyand then upwardly to form a groove, the ange on the bottom of said unit being bent upon itself to form a tongue and a. rim extending at right angles to the ange from the top of said groove and the bottom of said tongue.
